KNQCKDOWN BOX.

To all whom it may concern:

Be it known that 1, WILLIAM E. INGRA- HAM, a citizen of the United States, residing at Redondo Beach, in the county of Los Angeles, State of California, have invented new and useful Improvements in Knockdown Boxes, of which the following is a specification.

This invention relates to a knock-down box or crate. Y 7

It is the object of this invention to provide a box or crate in-which the sides, ends, top and bottom members maybe separated and stacked to render the box compact when not in use and to economize space in shipping same.

Another object is to provide an eifective means fordetachably connecting the various members of the box together to form a rigid structure, with theparts securely connected together against displacement.

Another object is to provide a means for detachably locking the variousbox-members together, so constructed'and arranged that the box cannot be dismembered without first removing the top and bottom port ons thereof. 7 V

A further object is to provide a knock- .down box in which the use of hinged connections and spring clips is obviated and in which the connection between the various box members is effected by means of a headed pin and slot construction.

The invention is illustrated in the accom panying drawings, in which: Figure 1 is .a perspective view of the box illustrating it as assembled and with parts broken away. Fig. 2 isa view in perspective ofthe'box cover as seen from its under side. Fig. 3 is a perspective view of one of the box ends. Fig. 4 is a perspective view "of one ofthe side members of the box. Fig. 5 is a detail in side elevation of the upper corner portion of the box, as seen in the direction indicated by the arrow 5 in Fig. 1, with parts broken away, illustrating the manner in which the cover of the box is applied and moved to its closed position. Fig. Sis a sectional view on the line 66.of Fig. 5, as seen in the direction indicated by the arrows. Fig. 7 is a view in perspective illustrating the box sections as dismembered and stacked in their knocked-down position. 7 More specifically, 10 and 11 indicate the top and bottom members of the box, which are of corresponding construction, and each Specification of Letters Patent.

termed key-h0le slots, adapted to: receive pins or studs, as will be later described. The panel 12 is formed with recesses 16 rearward of the key-hole slots to receive the headed studs engaged by the latter.

The box is provided with rectangular end panels 17 and 18 of complementary construction, which'panels are fitted with me- .tallic bands 19, extending around their edges, as particularly shown in Fig. 3. The

side panels 20 and 21 of the box are also rectangular in form and are fitted with me tallic bands 22, which extend around their edges and are also provided with plates 23,

mounted on one of their faces, which plates are arranged to extend adjacent the vertical edges of the side panels, as particularly shown in Fig. 4. The plates 23 are formed with alined key-hole slots 24, and the side panels are recessed behind the said slotsto receive headed studs 25, mounted on the vertical edgesof the end panels 17 and 18. The side panels 20 and 21 are provided with headed studs 26 on their upper and lower edges, which are adapted to extend into the key-hole slots formedon the top and bottom members 10 and 11. r

In assembling the box the side and end members are first connected together by introducing the headed studs 25 on the end members 17 and 18 into the key-hole slots 24 of the side members 20 and 21 and shifting the side and end members longitudinally in relation to each other to efiect the engagement of the headed studs 25 by the narrower portions of the key-hole slots 24.

The end panels 17 and 18 will then be positioned between the side panels 20 and 21 in the position shown in Fig. 1, and will be securely held in place by the pin and slot connection-The bottom panel 11 is then key-hole slots on the bottom member; the

headed portions of the studs being introduced through the perforations 14:, as shown in Fig. 5, whereupon the panel 12 is shifted from the position shown in full lines inFig.

to the position indicated in dotted lines therein, to dispose the headed portion of the studs 26 in engagement with the mar-' ginal edges of the slots 15, thus connecting the panel .l2'to the side and end members of the box. The top of the box is then placed in position in like manner. To securely hold the parts. against accidental disengagement, screw-headed bolts 27 are inserted through perforations 28 in V the top and bottom members 10 and 11 ad- 18 in like manner.

On removing the cover 10 and bottom mem-F ber 11, the side panels 20 and 21 may be disconnected from the end panels 17 and The side panels, end panels and top and bottom panelsare then Copies of this patent may be obtained forrfive cents each; by addre the various panelstor bind the latter to- .gethenas illustrated in Fig. 7; the various panels "being provided with a central perforation 32 to receive the bolt 30. What I' claim is:

A,.1mo.ck-down' ,box comprising compleanentary end panels, headed studs on the vertical edges of said end panels, threaded nuts arranged across vertically extending bores inthe top and bottom edges of the end panels, complementary SldQ panels, me'- tallic frames secured thereto having keyholeslots adapted to receive-and engage the headed studs on the end panels, headed studs on the upper and lower-edges of the -side panels, metallic frames on the complementary top and bottom panels having. keyhole slots adapted to receive and engage the headed studs on the side panels, and bolts adapted to be passed through the top-and bottom panels and threaded into engagestacked, shown in Fig, 7, 'and a bolt fitted with a nut 3l, is introduced through 35' ment with the nuts carried-by the end panels to lock the various panels' against displacement in relation to each other;
